Engines

 There are some different types of engines.

Here we're going to talk a bit about all of them

• Heat engine: It is an engine that transforms heat into mechanical work and has a hot and a cold source, the larger the difference of temperature between this  sources, the larger the energy produced.

• Electric motor: It is an engine that uses electrical energy to obtain mechanical energy by the interaction of magnetic fields.

• Physically powered motor: It is powered by kinetic or potential energy. There are two types of physically powered motors:

1.   Pneumatic motor: It converts potential energy (compressed air) into mechanical energy through linear or rotatory motion.
2. Hydraulic motor: It converts hydraulic energy into mechanical energy
